Be it known that I, FRANK J. REINHOLD, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Nailing or Stapling Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to a hand nailingimplement especially designed to be used as a means for uniting the ends of belts and for other like purposes; and the invention consists in the peculiar construction, arrangement, and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of my improved device. Fig. 2 is a longitudinal section thereof, showing the implement as in use. Fig. 3 is a perspective view of the forward end of the staple-receptacle. Fig. 4 is a perspective view of the adjacent ends of the staple-receptacle and spring-box. Fig. 5 is a cross-section on line w m, Fig. 1. Fig. 6 is a side elevation of the operating mechanism for the pluugers.

My device comprises a bifurcated frame forming a pair of fixed jaws A and B, separated from each other by the slot 0, adapted to receive the work to be fastened together. The jaw A is hollow, forming a magazine for the nails provided at its'rear end with the removable cover D, through which the nails may be introduced.

In the drawings I have shown my device adapted to use staples, which are preferably put up in the form of rectangular packages E, made of sheet metal, cardboard, or other thin material and adapted to be slipped into the magazine. The rear ends of these packages are open to admit spring-pressed follower F, but are provided with retaining lugs or flanges a, adapted to hold the staples in the package. The follower F is preferably formed integral with the spring-casin g F, containing the spring G, and is of a shape and size to freely enter the end of the package and bear against the rear staple, the rear end of the spring abutting against the cover D.

H is a slot in the forward end of the jaw A, and I is a slot in the jaw 13 in line with the slot H. In these slots are slidingly secured the dies or plungers J K, the former adapted to force the staple through the Work and the latter to clench the same.

The slot I has the tapered portion at its upper end forminginclined shoulders I), adapted to turn the ends of the staple toward each other and into the path of the die K.

Land M are levers fulcrumed to the jaws A'and B and connected at their outer ends to the dies J and K, respectively.

N is a ratchet-wheel pivoted upon the pin 0, secured to the bifurcated frame.

P and Q are cams secured to the ratchetwheel N, adapted to bear against the rear,

ends of the levers L and M, respectively.

B is an arm pivoted to the pin 0 and extending rearwardly therefrom, being prefer ably provided at its free end with an eye or thumb-hold R.

S is a pawl pivoted to the arm R, adapted to engage with the ratchet-wheel N.

T is a holding-pawl for the ratchet-wheel pivotally secured to the frame, said pawls S and T being provided with suitable springs (not shown) for holding them normally in engagement with theratchet-wheel.

c is an arm on the pawl S, adapted when the arm R is thrown back to strike against the pin cZ and disengage the pawl from the ratchet-wheel, and e is a lug on the arm R, adapted at the same time to strike the arm f on the pawl T to disengage the latter pawl from the raichetavheel.

The parts being constructed as shown and described, to use the device the operator first removes the cover D and places a packageE of the nails-or staples in the magazine, next introducing the follower F and spring G, and then securing the cover D in position. The pressure of the spring will force the package to the forward end of the magazine into the path of the die or plunger J, which is normally withdrawn by the tension of a spring, such as U, attached to the levers L and M. The operator now grasps the rear end of the bifurcated frame, placing his thumb through the eye R of the arm R and introducing the ends of the belt or article to be fastened into the slot C. By now operating the arm Rthe ratchet-Wheel N and cams P and Q, are turned by a stepby-step movement, the pawl T preventing them from slipping back when a new hold is taken by the pawl S. The arrange ment of the cams P and Q is such as to suecessively operate the levers L and M, and as the plunger J is pressed down by the former it will cut through the package E, forcing the first staple out through the slot H and through the work, the ends being turned in by the inclined shoulders I). The lever M will then force up the die or plunger K, firmly clenching the ends of the staple. The operator may now throw back the arm R to the point where the arms 0 and f of the pawls will come in contact with the pin d and lug e, which will disengage both pawls from the ratchet-wheel, allowing the parts to be returned to their initial positions by the spring U. As soon as the plunger J is withdrawn from the magazine the spring G, pressing upon the follower F, will force the staples forward in the package, bringing another one into the path of the plunger. To enable the plunger to readily cut through the end of the package, I preferably provide the former with the cutting edges 9 and cut away the ends of the pack age, as shown in Fig. 3, leaving only the reraining-points h to be cut by the plunger.

By providing the device with the step-bystep operating mechanism shown I am enabled to secure great power, which will render the operation easy even when the nails are forced through tough material offering great resistance.

Although I have described my device as especially designed for securing belts, it is obvious that it is equally well adapted for many other purposes.

That I claim as my invention is- 1. In a hand nailing implement, the combination with a frame provided with a pair of fixed separated jaws forming respectively the nail-holder and one handle, and the rest for the work; of plungers or dies slidingly secured in said jaws, the one adapted to press the nail through the work and the other to clench the nail; levers for operating the plungers pivoted on said frame; means for differentially operating said levers; and an arm, complementary to the handle, on the frame and independent of the levers for operating the said means, substantially as set forth.

2. In a hand nailing implement, the combination with a handle or frame provided with a pair of fixed separated jaws, forming respectively the nail-holder and a rest for the work, of plungers or dies slidingly secured in said jaws, the one adapted to press the nail through the work and the other to clench the same, and means for operating said plungers successively by a step-by-step movement.

3. In a hand nailing implement, the combination with a handle or frame, provided with a pair of fixed separated jaws forming respectively a nail-holder and a rest for the work, of plungers or dies slidingly secured in said jaws, the one adapted to press the nails through the work and the other to clench the same, and means for successively operating said plunger, comprising the levers L and M pivotally secured to the jaws and respectively connected to the plungers, the pivoted ratchetwheel N carrying the cams P and-Q adapted to engage with the levers L and M, the rockarm R carrying the pawl S and the holdingpawl T, substantially as described.

at. In a hand nailing implement, the combination with a handle or frame provided with a pair of fixed separated jaws, and a magazine formed in one of said jaws adapted to receive a package containing the nails, of a plunger or die slidingly secured in said magazine-j aw adapted to cut through the nailpackage and successively force the nails from the magazine through the work, a clenching die or plunger secured in the opposite jaw, and means for operating said plungers successively.

5. In a hand nailing implement, the combination with a handle or frame provided with a pair of fixed separated jaws, and a magazine formed in one of said jaws adapted to receive a package containing the nails, of a plunger or die slidingly secured in said magazine-j aw adapted to cut through the end of the package and force the first nail from the magazine through the work, a spring-pressed follower in the magazine adapted to enter the rear end of the package and force the nails successively into the path of said plunger, a clenching die or plunger in the opposite jaw, and means for operating said plungers successively.

In testimony whereof I afiix my signature in presence of two witnesses.
